IMPROVEMENT IN PUMPS.

l 'Specification forming part of -Letfms Patent No. 4 l ,291, datedJanuary 19, 1864.`

To all whom it may, concern,.-

Be it known that l, J oHN G. GARnErsoN,

of Salem, in the county of Henry and Stateof Iowa, have invented a newand useful'lmprovement in Force-Pumps; and l do hereby declare that thefol-lowing is a full and exact, description thereof', reference beinghad to the' accompanying 'drawings and thenlet'ters of reference, markedthereon, in whichl Figure lis a vertical elevation and outside View ofthe whole `pump ready for use, with a wooden stem, K, as a support totheV handle, which is now supposed to be descendit] g. Fig, 2 is alongitudinal seetionalview showing the plunger within the cylinder andthe'partit-ion marked e dividing' the` tube c in two equal he positionhere shown is that of the' Partsdownward movement ofthehandleand ascentof tlieplunger-jf Fig. 5 -isthe same ricnrprc# 4cisely, only the handleis supposed to be lifted,

and thereby forcing the pipe l) to the opposite side of the .pipe C toreceive the water from below the plunger. n i

' The peculiarity of my'inrention consists in making that part of thetube c entering into the cylinder and connecting with the plunger Bdoublc-t hat js, divided longitudinally inte two equal parts by thepartition c terminating at g, while the pipe D is a single't'ube and lof the pipe, while the other is left open to revceive the-Water, thecurrents Vot which are vclearly indicated bythe arrows, as seen in Figs.2 and 3.

'lo enable others skilled inthe art to make and. use my pump, Iwi-l-lmore particularly describe the saine, referring to the drawings land the letters thereon.

A, Fig. l, is thc'c'ylinder or p u mp-barrel say four inches in diameterand seven or eight yinches long-as adapted to wells twenty-tlve orythirty feet deep, made ot' iron, brass, or yother suitable material,and when put together has only one opening, and that is where the tubec, Fig. 2, enters, on the lower end of which Y is seen the plunger B',Figs. 2 and 3, and at p to form a pivot to the links it', which may be'about one and three-fourths inch long from center to'center. The otherend of these links is pivoted at f, which is tirmlyfconnected with lthepipe I), extending to the top of vthe well, l where it is fastened tothe handle H, Fig.l 1.

tube from the plunger B to the top of the well,v

the 'Water now passing out of the' upper part oftheI cyliuderintli'edirection indicated by the arrows. AThen by lifting up the handlethe pressure falls on the links i i and brings f and g as near togetheras they can come un'til the pipe. D is arrested in its further lat eralprogress by coming in contact with the other side of the pipe C andpartition e, as will be better seen in the position 'of Fig. 3, thusforming a continuous tu'be from the plunger B to the top of the well.Thus alternately bearing down and lifting the handle, you change thepipe D from side to side, and always to that side next to 'discharge itswater, and so bring the water up in almost direct lines, Without quirksor short turns` :and completely dispensing with anything like Valve orcut-ot,and

forming a double-acting forcepumpfyielding a nearly or quite continuousstream of water while in aotion,but when left at rest immediately letsall its water descend t a common level, that being1 useful in summer tokeep the water cool, and in winter to prevent its freezing. This pump,being a force-pump, must be immersed in the water, and as it receivesits water fromthe topis not likely to be obstructed by gravel or mudbeing drawn into the cylinder.

l contemplate using my pump in all situations where water is to bebrought from a lowerto a higher level ot' any height, having duereference to the well-known iawsof hyl draulios in adapting the diameterof the cylinder and length of the stroke to the heightthe water has tobe raised. I also propose adapting my invention to fire-engines.'

What Iolaiim as my invention, and desire to secure bylietters Patent,is-

The joint formed by the parts f en@ g with the links i ,Fig. l7 in theposition shown in thedrawings when acted onby the handie'H,

Fig. 1K,` and made to move the pipe D alter- `double-acting force-pumpwithout valve orA cut-oit.
